half an onion
1 clove of garlic
1 pinch of ground cumin
1lt of stock, brought is good, homemade is better (veggie for vegans, chicken for others).
salt and pepper
1/2 cup of soy or rice milk (optional if blending)
Wash the leeks, then Chop up them up along with the onion, and potato, I like to leave the skin on the potatoes.
Garnish with chives. That's it, super easy, super good.
